  • Top of rail lubricating method and composition
    Patent number: 5492642
    Abstract: An aqueous top of rail lubricant comprises a synthetic lubricant, a synthetic thickener, propylene glycol and ethanol. The lubricating composition is consumed in 5 to 15 minutes in the heat generated by a passing train. The lubricant is environmentally innocuous.

  • Preparation of high dropping point lithium complex soap grease
    Patent number: 4582619
    Abstract: A high temperature multipurpose grease is prepared from the lithium soap of a C.sub.12 to C.sub.24 hydroxy fatty acid, (e.g. 12-hydroxy stearic acid) and a dilithium soap of a C.sub.4 to C.sub.12 dicarboxylic acid, (e.g. dilithium azelate) wherein the acid mole ratios range from 3:1 to 0.5:1 respectively under carefully controlled processing conditions including controlled alkali addition and one step heating.

  • Lithium soap grease additive
    Patent number: 4536308
    Abstract: An experimental grease has been formulated with 8.5 wt % lithium 12-hydroxystearate in a base oil containing an additive composition of a synergistic blend of zinc dialkyldithiophosphates, zinc diamyldithiocarbamate, aromatic amine phosphate, sulfurized sperm oil substitute and the reaction product of coconut oil and diethanolamine.The lithium 12-hydroxystearate grease has been prepared by a standard kettle procedure. The grease composition exhibits a dropping point in the range expected of a lithium complex grease. The grease keeps its soap fiber structure intact at 390.degree. to 400.degree. F., typical of the melting range of lithium 12-hydroxystearate greases.The grease is useful for its long life in constant velocity joints.
